I've just added this, and a few more pics of this to my project journal.

Yes, you're correct on both counts.
I used (expensive) ball valves like these ones on each of those 4 locations, and came up with a conglomeration of sweat-on fittings (don't trust compression fittings with 125 PSI) with swivels to allow for dissasembly if needed.
I pretty much cleaned out the local plumbing supply ...

A little later on, I found some sweat-on mini valves and used them for the outlet drops. Yes, every outlet has a drop and a ball valve so that moisture can be ejected.

Maybe I'll take some more pics after I clean up my messy garage. LOL

Yes it has ball valves on every vertical drop.

Very little moisture ever makes it to the water trap.

I did one just like yours 66. I can run my blasting cabinate now that I did. It works great at a good cost.

How much pressure is a trans cooler designed to handle?

Got a new camera,see if this works.One is the "infamous" Franzinator....with external cooling coil(total loss system,IOWs 1/4" tubing taps into water supply but instead of tying back in,it simply fills a bucket.Only use this when AC is runnin non-stop.....and the water is simply adj to dribble).

The other pic is a copper coil.Its 3/4 that was simply coiled around a big sander drum or sumthing?Anyway its gonna be installed after comp.....

I need to tig up another expansion chamber on comp outlet...then plumb the above coil in....just need the time to do it....duh.

Good luck with your system.

I am thinking going up the wall from my compressor to the cooler, then out of the cooler down to a tee w/a leg w/a drain at the end, then back to the tank.

That will work but I think you may get more water than you think. I would be tempted to pick up a 10 gallon air tank and run through it to catch the condensation.

Please let us know how it works out.

Of course you are right. I engaged my typing finger before I put my brain in gear. I was thinking of automotive unit. I would think the home evaporator would work great. You would need to have a small tank to catch the water before it got to your compressor tank but that should not be too hard to find either. This is something I have also wanted to do. I hope you will post your progress along with a few pictures as you go. Good luck.

As far as restrictions go, it looks to be ok. It has a 3/8(I think) small line going in and that splits off into smaller 1/4(I think) lines an goes into the core.
The a-coil is the evaporator portion that is in the house above the furnace fan. The condensor is the part outside and would be way too big to mount anywhere. I have that unit also and was going to scrap it.

Is the A coil the condenser or the evaporator? I would think the condenser would be more effective though either would be an improvement. You will also need a catch tank for the water that will condense out as the air cools.

Of course I would have to eliminate the expansion valve on the a-coil to remove that restriction.
Any thoughts?

The only things I can think of are 1) be sure the coil is internally clean and 2) what's the tube size? If it's too small, it could be a restriction to flow rate.

Home A/C a-coil for a air compressor air dryer?
